TELEPHONE ATTACHMENT.

Specification of Letters Patent.

Patented Dec. 26, 1905.

Application filed February 24, 1905. Serial No. 24:7,126.

To all whmn, it may concern:

Be it'known that 1, PAUL KAMMERER, a citi- Zen of the United States of imerica, residing at Pittsburg, in the county of Allegheny and State of Pennsylvania, have invented certain new and useful Improvements in Telephone Attachments, -of which the following is a specification, reference being had therein to the accompanying drawings.

This invention relates to certain new and useful improvements in telephone attachments, and relates more particularly to aregister for indicating the number of calls that have been transmitted over the telephone to which it is attached.

The object of .this invention is to provide a novel form of attachment that can be easily and quickly secured to the transmitter-arm of a telephone, and, in connection with the attachment, I emply a register, which is adapted to be actuated by the person transmitting a message, each time the telephone is used.

By my improved register it will be possible to keep an accurate account of the number of calls transmitted over a telephone, and the register is adapted to prevent the company controlling the telephone from exaggerating the number of calls made over such telephone.

"With the above and other objects in view the invention consists in the novel construction, combination, and arrangement of parts, which will be hereinafter fully described and then specifially pointed out in the claims, and referring to the drawings accompanying this application, like numerals of reference designate correspondingparts throughout the several views, in which Figure 1 is a front view of a telephone-transmitter equipped with my improved attachment. Fig. 2 is a side elevation of the same. Fig. 3 is a transverse sectional view of the casing of my improved attachment, illustrating aregister mounted therein. Fig/Lis a similar view with the register thereof detached. Fig. 5 is a vertical sectional view of the casing. Fig. 6 is a rear view of the same, and Fig. 7 is perspective view of my improved attachment.

To demonstrate the use of myimproved telephone attachment, I have illustrated the same in connection with a transmitter-arm 1, upon which the bracket illustrated in Fig. 1 of the drawings is adapted to be clamped. The bracket comprises a substantially U-shaped body portion 2, the sides of which are provided with horiZontally-alined apertures 3 3, and when the bracket has been placed upon the arm 1 of the telephone a bolt and nut 101' the like fastening means is employed for securing the bracket thereon. The rear edge of the bracket is provided with a standard 5, having apertures 6 6 formed therein. These apertures are employed to secure the casing 7 to the standard. suitable means, such as screws 8, being employed.

The casing 7 is substantially cylindrical in form and comprises a front wall 8', having a slot 9' formed therein. The rear edges of the sides of the casing 7 are flanged, as indicated at 10, and provided with inwardly-extending pierced lugs 11 11 and outwardly-extending pierced lugs 12 12. The outwardly-extending lugs 12 12 are employed for securing the casing to the standard 5, and the screws 8 are adapted to pass through the pierced lugs and engage in the apertures 6 of said standard.

The reference-numeral 14 designates a register, which I desire to employ in connection with my improved attachment. This register is of the ordinary construction and of a con- Ventional form that need not be further described, with the exception that the same is provided with an actuating-lever 15, that is adapted to protrude through an opening 16, formed in the side wall of thecasing 7.

In Fig. 2 of the drawings 1 have illustrated the relative position of the attachment to the transmitter-funnel of the arm 1, and the juxtaposition of the register enables a person transmitting a message over the telephone to conveniently operate the register. The register is adapted to be operated each time a message is transmitted over the telephone, and the lever 15 is adapted to be actuated by the person transmitting the message. The position of the register permits of the number of calls indicated by the register always being observed by persons in the vicinity of the telephone, and it can always be observed whether the person transmitting the message has registered their call.

I may use any form or type of registering mechanism in connection with my improved attachment, and I do not care to confine myself to the form or type of register shown in the accompanying drawings.

It will be noted that various changes may be made in the details of construction without departing from the general spirit and scope of the invention. For example, the attachment may be slightly modified, so as to be securely attached to desk-telephones or other forms of telephones in use.

WVhat I claim, and desire to secure by Letters Patent, is

1. In an attachment for telephones, the combination with a transmitter-arm, of a standard formed at its lower end with an inverted-U- shaped bracket adapted to span and be clamped to the transmitter-arm, a casing having outwardly-extending pierced lugs secured to said standard and provided with inwardly-extending pierced lugs, and registering mechanism secured to said inwardly-extending lugs, and a lever for actuating said mechanism extending through a slot provided therefor in the wall of said casing.
